ROLL non PAPER-MAKING MACHINES.

Specification of Letters Patent.

Patented Sept. 11, 191%.

Application filed January 4, 1917. Serial No. 140,537.

To all whom it may concern:

Be it known that I, HILAND R. FARNs- WORTH, of Sandusky, county of Erie, and State of Ohio, have invented certain new and useful Improvements in Rolls for Paper-Making Machines, of which the following is a specification.

This invention relates to the construction of rollers for use in paper mills or an other place where they are suitably adapte Heretofore, it has been the common practies to make the rolls, usually called felt rolls, for use in aper making, of wood, iron or brass.

My invention comprises a roll made up of blocks or sections of paper pulp suitably secured together, or, if desired, the roll may be made in a single piece of paper pulp, as will be fully set forth in the specifica tion and claim.

Referring to the drawings:

Figure 1 is a side elevational view partially in section. showing the manner in which the blocks or sections of paper pulp are secured to ether;

Fig. 2 is a transverse sectional view on the line 22 of Fig. 1, showing a plurality of tubes for holding the two end plates together, which in turn securely clamp the blocks in place, also the opening through the center portion of the disk.

Referring to the drawings in detail: 1 designates the blocks or sections of paper pulp which compose the roll. These sections are held in place by means of the tubular or pipe sections 2 three of which are shown and which carry collars 3 at their outer ends. 4 designates heads or plates, preferably of cast iron, through which the pipes 2 extend- Engaging the outer ends of the caps t are nuts 5 which are screwthreaded onto the ends of the pipes 2, whereby when these nuts are turned up the caps will engage the collars and force the blocks or sections of paper pulp toward each other, thus rigidly holding them in place. These blocks are preferably composed of paper pulp sections which are sub- .jected to great pressure, by hydraulicmeans The pulp may be mixed with if desired. a water resisting substance, as sizing or pitch. These rolls as made up of paper pulp are very much cheaper than making them of wood, iron or brass. At the present time wood of the desired quality is hard to obtain, the iron rusts and the brass is expensive. ,The present invention is, there fore, intended to make up a roll adapted for felt rolls. Secured to the heads l are caps 6 by means of the set screws 7 which engage the hub portion of the cap plates which cover the nuts 5. Rigidly secured in the hub of the plates are journals or shafts 8. Each of the disks or sections is formed with an opening 9 whereby the disk or blocks are resilient to lateral pressure.

WVhile I have described my improvement in rolls as composed of blocks or sections made of paper pulp it is evident that these sections may be made of other inexpensive material which would serve the same purpose, as fibers of different kinds. It is to be understood that the roll is not limited for use in paper making machines, as there may be other places in the arts where such a roll could be used to advantage.

lVhat I claim is:

A roll of the kind described, comprising a plurality of perforated sections having an opening through their centers, means for securing the sections together, comprising a plurality of tubes extending through other openings in the sections and parallel with the center openings, heads or plates to which the ends of the tubes are connected, journals secured to the heads for permitting rotation of the roll, said sections being composed ofelastic fibrous material, as wood pulp, and treated with a water resisting or sizing substance, as pitch.
